RX50 is single-sided, 96TPI, 250KHz MFM, 512-byte sectors, 10
sectors/track. There's software interleave. The disks are not MS-DOS
formatted, so mtools won't be able to do much with them. WPS also uses
the floppies in "12-bit mode" (the DECmate is a 12-bit machine), which
also has implications for the floppy format (basically, only 12 out of
every 16 bits is valid, but I don't know how they're distributed
throughout the diskette).
